High load current is only one of several problems that the electric motor shows. Despite being a single problem, the possible causes may be different and these reasons may be: voltage outside the nominal, overload, frequency outside the nominal, very stretched belt or rotor stator dragging.

The electric motor can also present as a problem low electrical resistance and this unfortunate the electric motor can be driven by damaged slot insulation, cut cabinhos, coil head abutting the carcass presence of moisture or chemicals, or even presence of powder on the wound.

bearings of heating is also an electric motor problem. This problem can be caused by excessive axial or radial belt, the shaft is bent, the covers can be decentralized or loose, there is grease in excess or lack of grease or grease was inserted with foreign material.

The electric motor can also get overheated because the ventilation was obstructed, the electric motor has a smaller fan than indicated, voltage or frequency are out of the specified, the rotor is failing or dragging, the stator is without impregnation, is overloaded, the bearing is defective, the matches are consecutive, the air gap is below the specified, inadequate permanent capacitor and connections are wrong.

Upon reaching the rated speed, the electric motor should have initiated the short-circuiting procedure of the collector rings and fires the lifting device and the short-circuiting in the opposite direction, through the electromechanical actuator or manual way through wheel.

The short-circuit the electric motor px 120 coupling is made through the bushing slide and which is able to withstand the silver contacts and only after that fires the lifting mechanism of electric motor brushes. When brushes incorporating the electric motor are fully raised, the device will shut off automatically, through the ECC key.

The automotático system that raises the electric motor brushes of the electric motor comprises a autuador overloaded electromechanical protection system actuation by means of torque wrenches to overload during lowering or lifting the brushes is switched off.

Before starting the electric motor to work, the ideal is to verify that the keys CLD, CLE, CCD and CCE are connected in the right way panel.

The ways of using the electric motor won the news over the years and now the machine shows better and serving segments increasingly different. When this machine was built, she could only meet the industrial segments, such processes were heavy they used the electric motor to ensure efficiency and greater economy.

With passing years the machine was gaining new models and today it can be found in very different purposes. Elevators, home appliances and even vehicles make use of the engine to operate. It has a very important function and there are several other machines that also perform the same process except that not everyone can offer all the benefits of an electric motor can.

The electric motor’s dodge coupling px80 function is to make the transformation of electrical energy to mechanical energy, so that various products and processes using this machine because they need to have this feature in order to function, as the most economical electric motor it is more choice.

You can find free course electric motor being taught by various educational institutions. Institutions known as Senai or Senac are among those that offer courses at no cost and are facing area of ​​electric motors. It is worth taking a look if in your area have any open class for these courses.

When choosing a course so you can learn about electric motors makes all the difference to choose an institution that offers courses at no cost. Many of these courses are geared to low-income people or workers in some commercial or industrial segments, always it depends heavily on the partnership that the institution made the workplace.

The free courses offered are complete and taught by great professionals, but so you can find all these benefits you have to search a lot and read about the institution that is teaching the course. In addition to the free courses, you can also find those courses that are paid, they already have values ​​that depend heavily on the institution that is teaching the same.

Remanufactured electric motor should provide all the conditions when it was bought in the factory reelcraft 650 mro supply

After an electric motor being refurbished, the ideal is to check whether the electric motor has all the original conditions of performance when purchased at the factory.

To have access to this data, it is important that companies have the record of the original data stream and use the vacuum of each electric motor and which is carried out a comparison after the electric motor be subjected to repair.

If the electric motor has increasing power and consumption in empty, indicated is to replace the electric motor has been repaired by a new electric motor, because the new electric motor has longer life, rapid return on investment and also a considerable energy savings.

It is common for these records of current data on empty and consumption are not recorded by the company and to make this analysis is possible to use characteristic curves that are provided by the electric motor manufacturer so that the comparison is made.

Simple but of fundamental importance for the life car engine care is: do the recommended revisions by the manufacturer care when starting the vehicle and while driving are some important tips.

The act of taking care of the car engine is directly related to follow what the manufacturer indicates and do all recommended revisions, as well as take care of the car engine, makes the owner save, not having to shell out a large sum for lack preventive maintenance.

When the car is turned on and the outside temperature is too low, the tip is to wait a bit before starting the car by putting the car engine. This time is important, as liquids will lubricate all car and the car will be safe and trouble-free.

Posted onFebruary 26, 2016|Comments Off on Learn about the problems that can be caused to the electric motor due to the imbalance of tensions

The imbalance of tensions can be caused by using cables that have different yardsticks and this will cause the three-phase network suffers with the imbalance or also by an unbalanced connection of single-phase loads.

The imbalance of tensions brings many problems for the electric motor and the network as a whole and these problems are: waste of energy due to the existence of major losses caused by high currents unbalanced (reduction in income); temperature rise above acceptable limits by the electric motor; reducing the torque available to the load, the existence of the magnetic field component spinning in the opposite direction to the electric motor rotation and reduction, however small, power factor.

To fix these problems you need to: use three-phase motors; balance the lighting circuits to obtain loads evenly distributed among the three phases; the circuits, using the same conductors gauge and length and seamless in three phases, and also verify that all bank capacitors are working properly.
